问题
I have a database docker container that is writing its data to another data-only container. The data-only container has a volume where it stores the data of the database. Is there a "docker" way of migrating this data-only container from one machine to another? I read about docker save and docker load but these commands save and load images, not containers. I want to be able to package the docker container along with its volumes and move it to another machine.

Checkout the flocker project. Very interesting solution to this problem, using ZFS to snapshot and replicate the storage volume between hosts.
